Answer:

AH! Quadratic Equations?!?!?!??

Step-by-step explanation:

The discriminant is the this part of the quadratic formula(the one in parentheses)

x=\frac{-b+-(\sqrt{b^{2}-4ac }) }{2a}

So let's take it out!

b^{2} -4ac

(if you don't know what a quadratic equation is, why are you doing this to yourself?)

REMINDER: Quadratic equation: x^2+bx+c=0

So let's input the values into this and find out!

It is more likely that the last three will have a negative discriminate so:

3:

49-12

37

Nope! Positive!

4:

16+8

Nope!Positive!

5:

9-16

Found It!

Hope this helps.

FYI it's option 5

Solve the following system of equations and show all work. <br> y = x^2 + 3<br> y = x + 5
RUDIKE [14]
Since both of the equations are equal to y...set them equal to each other.. So it will then be

x^2+3=x+5
      -3     -3
x^2=x+2    ---> x^2-x-2
                       (x-2) (x+1)
                        x=2,-1

The graph models function R. The table of values models function S. Which statement is true about these functions?
vagabundo [1.1K]

Answer: OPTION D.

Step-by-step explanation:

The rate of change of a linear function is also known as "Slope".

The slope can be calculated with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

Choose two points on the function "R" graphed:

(1,0)\\(0,-3)

You can say that:

 y_2=-3\\y_1=0\\\\x_2=0\\x_1=1

Substituting values into the formula, you get:

m=\frac{-3-0}{0-1}=3

Choose two point from the table that models the function "S":

(4,21)\\(6,31)

You can say that:

 y_2=31\\y_1=21\\\\x_2=6\\x_1=4

Substituting values into the formula, you get:

m=\frac{31-21}{6-4}=5

Therefore, you can conclude that the function "S" has a greater rate of change than Function "R".
